Description

In the Linux kernel, the following vulnerability has been resolved: jfs: fix uninitialized waitqueue in transaction manager The transaction manager initialization in txInit() was not properly initializing TxBlock[0].waitor waitqueue, causing a crash when txEnd(0) is called on read-only filesystems. When a filesystem is mounted read-only, txBegin() returns tid=0 to indicate no transaction. However, txEnd(0) still gets called and tries to access TxBlock[0].waitor via tid_to_tblock(0), but this waitqueue was never initialized because the initialization loop started at index 1 instead of 0. This causes a 'non-static key' lockdep warning and system crash: INFO: trying to register non-static key in txEnd Fix by ensuring all transaction blocks including TxBlock[0] have their waitqueues properly initialized during txInit().
